Title: Method and device of bending material
Inventor: YONEYAMA KENJI
IPC: B21D9/01
Filed: 1999-01-11
Abstract: PROBLEM TO BE SOLVED: To enable bending of a long workpiece formed with a hollow in the core, without causing defects like flattening or wrinkled deformation due to bending stress. SOLUTION: A workpiece of a hollow material is held by a tensile holding member 8 and advance along the outer circumferential surface 4a of a forming drum 4. In this case, flattening deformation can be controlled by using a core material I. In addition, a pressurizing force F is imparted to the surface of the work W by means of pressure shoes 13, 14, actuating a dynamic friction resistance to the surface. As a result, the workpiece W is given a bending moment while a tensile stress is given in the axial direction; therefore, a compression stress component within the bending stress is relaxed. Thus, there is less tendency to cause wrinkled deformation in the cross section.

IPC: G11B7/085
Filed: 1986-01-14
Abstract: PURPOSE:To prevent the recording mistakes, etc., by detecting a track jump with the track crossing signal and changing the light power of a laser light source to a non-recording state from a recording state. CONSTITUTION:The tracking error signal 27 of a two split photodetector 26 is turned into a track crossing signal when a track jump occurs. The track jump detecting signal is obtained by comparing the waveforms of the signal 27 with each other through a positive comparator 32 and a negative comparator 33 respectively in terms of each threshold value. Then an OR is secured for the track jump detecting signal through an OR gate 36 is opened to cut off a recording signal generating circuit 31 and a semiconductor laser driving circuit 30. At the same time, the light power of the circuit 30 is reduced to the reproduction power. Thus the misrecording and double recording actions are avoided and the reliability is improved for the recording data on an optical disk.
